Supported notation formats

A number of formats are supported for reading and writing coordinate locations from a text string.

Degree-based formats

Both <longitude/latitude> and <latitude/longitude> are supported.

Decimal Degrees

Input formats for Decimal Degrees (DD) are as follows:

  • <latitude> <coord-pair-separator> <longitude>
  • <longitude> <coord-pair-separator> <latitude>

latitude

[ + | - | N | S ]<DD.dd>[ + | - | N | S ]

Case is ignored.

longitude

[ + | - | E | W ]<DDD.dd>[ + | - | E | W ]

Case is ignored.

coord-pair-separator

[space | / | \ | | | , | ; | : ]

Can be more than one separator, for example, comma space, space space.

Latitude <DD.dd> and longitude <DDD.dd> values can be formatted as follows:

Military Grid Reference System

Given the Military Grid Reference System (MGRS) coordinate, ZZBGGEEEEENNNNN, the various coordinate components are as follows:

  • ZZ: UTM zone
  • B: Latitude band
  • GG: Letters representing a 100,000-grid square (Universal Polar Stereographic area for polar regions)
  • EEEEE: X-coordinate (easting)
  • NNNNN: Y-coordinate (northing)

Spaces are allowed on input to Coordinate Conversion between the Grid Zone Designator (ZZB), 100,000-grid square (GG), easting (EEEEE), and northing (NNNNN). The number of digits used for eastings and northings must match. For example, all of the following inputs are equivalent:

  • 11SWC8081751205
  • 11S WC8081751205
  • 11S WC 8081751205
  • 11S WC 80817 51205

MGRS coordinates may be rounded to reflect lesser precision, for example:

  • 11SWC8081751205 is at 1-meter refinement.
  • 11SWC80815120 is at 10-meter refinement.
  • 11SWC808512 is at 100-meter refinement.
  • 11SWC8051 is at 1,000-meter refinement.
  • 11SWC85 is at 10,000-meter refinement.
  • 11SWC is at 100,000-meter refinement.

Coordinate Conversion only supports MGRS in the New Style lettering scheme based on WGS 1984.

United States National Grid

The United States National Grid (USNG) coordinate notation format is a simplified version of MGRS based on the United States National Grid. The components, space formatting, and precision follow the conventions of MGRS, which is explained above for reference.

Universal Transverse Mercator

The Universal Transverse Mercator (UTM) system is a specialized application of the transverse Mercator projection. The globe is divided into 60 north and south zones, each spanning 6 degrees of longitude. Each zone has its own central meridian. Zones 1N and 1S start at 180 degrees west. The limits of each zone are 84 degrees north and 80 degrees south, with the division between north and south zones occurring at the equator.

Given the UTM coordinate, ZZB EEEEEE NNNNNNN, the various components are as follows:

  • ZZ: UTM zone
  • B: Latitude band (Coordinate Conversion uses a latitude band and not N or S to represent a north or south UTM zone.)
  • GG: Letters representing a 100,000-grid square (Universal Polar Stereographic area for polar regions)
  • EEEEEE: X-coordinate (easting)
  • NNNNNNN: Y-coordinate (northing)

To input a UTM coordinate to Coordinate Conversion, spaces must be embedded between the UTM zone/latitude band (ZZB), easting (EEEEEE), and northing (NNNNNNN) components, and must be listed in this order: ZZB EEEEEE NNNNNNN (for example, 11S 369420 3763875).
